Go underground, deep into history

Four posters from the video game Portal 2

Hang them up anywhere you need more SCIENCE

Beware of combustible lemons, inhaling toxins

Portal 2 reinforced something we’ve known for a long time. To dig into history,one must go underground. Look at the the traditional room known as the Man Cave. Where is it? In the basement - underground! What do we do in a man cave? We grab our video game controllers and shoot at the bad guys in a historical war or we roll dice and pretend to fight dragons in a time long, long ago. It’s all making sense.

And Cave Johnson - oh, you didn’t realize how apropos his name is? - had his lair underground at Aperture Science. Decorate your man (or grrl!) cave to look like the older incarnation of Aperture with this set of four posters. The Portal 2 Underground Poster Kit includes one of each of the following posters: 1940s Aperture Signs, 1980s Boss Robot, 1980s Four Office, and 1870s Mannequin. Now get back to work on that combustible lemon!
